composite because it has more than two factors
21, 55, 77, and 93 are composite numbers. 23 is a prime.
Any of its factors including itself As a product of its prime factors: 5*11 = 55
4, composite. 67, prime.
Prime numbers are numbers that can only be multiplied itself and one.For ex.87 is a prime number. You can't multiply a number to get 87. Composite is a number that can be multiplied by other numbers than itself. For ex.55 is a commposite number. 11 and 5 can get you 55. Hope u understand! Good luck!

27 and 55 are composite numbers but 13 is a prime number
21, 55, 77, and 93 are composite numbers. 23 is a prime.
55 is a composite number because it has other factors aside from 1 and itself. The other factors of 55 are 5 and 11.
Prime factorization means to change a composite number into the product of its prime factors as for example 55 as a product of its prime factors is 5*11 = 55
55 has factors other than 1 and itself, so it is not a prime number. For example, 55 is divisible by 5. (You can tell this because the last digit is a 5. If the last digit - the digit in the ones place - is a 5 or a 0, the number is divisible by 5.) Therefore, 55 is a composite number.composite
Every number greater than 5 that ends in a 5 is a composite number, not a prime.
To find the prime factorization of a number, start with any factor pair of that number and keep factoring the composite numbers until all factors are prime. 55 5 x 11 = 55 Both factors are prime, so that is the prime factorization.

Answer:55 is not a prime number. It is a composite number.Definition:A prime number has exactly two factors: 1 (also known as unity) and itself. A composite number has more than two factors; in other words, it has at least one factor besides 1 and itself.Explanation:Any number ending in 0 or 5 is evenly divisible by 5, so it has 5 as a factor. Thus, 55 is also divisible by 5, so it is a composite number.
neither prime or composite
It is prime
